N 0. 880,603. Specification of Letters Patent. Patented March 3, 1908. v Application filed April 20. 1907. Suit-1N0. 369.249. 1

To all whom it may concern:

Be it known that I, WILLIs A. TREsoor'r,

I of Fairport, in. the county of Monroe and State or New York, have invented certain new and useful Improvements in Separating- Machines; and I do hereby declare the following to be a full, clear, and, exact description of the same, reference being bad to the ac-: companying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

This invention relates to separating ma- I chines for vegetables, fruit and the like, such as otatoes, oranges and apples, and articular y to that type of se arating mac ines in which the smaller articl s are caused to pass through openings in a separating element.

An object of my invention is to provide a separating-element which will have a maximum number of openings through which the smaller articlesinay pass, whereby a better separation will be secured without subjecting the articles to so much agitation which causes theni to become bruised.

Another object is to provide a movable agitator driven by toe separating element to lspense with unnecessary driving parts and to prevent the articles being SllbJGGlDBCl to sudden, sharp blows common to stationary or independently driven agitators.

Still another object is to provide a chute so constructed that it will be inexpensive to manufacture and will separate dirt and other extraneous matter from the articles.

A further object is to provide a ho )per which, While preventing the discharge 0 the articles through one wall thereof, will yield and ermit any articles, held by the belt, to pass ysaidwall.

A still further feature is the provision of a drivin means which may be under the full contro of the operator and will permit his 'su ervision of the material on the separating be t.

To these and other ends the invention consists of the arts and the combinations of parts shown in the accompanying drawings,

ereinafter described and more particularly pointed out in the ap ended claims.

In the drawings: liigure 1 is a top view of my invention; Fig. 2 is a transverse vertical section; Fig. 3 is a side elevation of the machine, parts being shown in section; Fig. 4 is a detail sectional view of the intermittent driving connection; Fig. 5 is a plan view of one of the rings of the separating element,

and Fig. 6 1s a. sectional view showing themanner of spacing the rings.

Similar reference numerals in the several figures indicate similar arts.

With .moreparticu ar reference to the drawings A indicates a frame which in the present instance comprises four uprights 1 suitably connected together at their up or ends by two longitudinal members 2 and a number of cross pieces 3. Supported on the upper art of the frame is a separating element which preferably is in the form of an endless belt and which comprises a plurality of parallel rows of rings 4 and means, as for instance, links 5, spacing said rin s at such distances that the s aces forme between every four rings will ave a width'approximately equal to the diameter of the space inclosed by each ring.

To prevent the ends of the links 5 injuring the articles to be separated or interfering with their passage through the ring spaces, and also to prevent the links sliding on. the rings and thus destroying the spaced relation of the latter, the rings are each provided with a plurality of eyes 6 in which the ends of the lmks 5 are secured. When the separating element is in the form of an endless belt, as shown in the tain of the links. are left 0 en, as at 5, so that by removing these lin be removed from the machine. belt is supported by a arranged rollers 7 and 8 journaled on the frame A at opposite ends thereof and carrying frusto-conical projections 9 which enter the spaces of the separator belt to drive the latter.

The mechanism for driving the belt is un der the full control of the operator and preferably comprises two tread ranged one on each side of the machine er:- tending longitudinally of the latter, and aving a common pivot 12. To hold the treadlcs The endless pair of horizontally in elevated positions two swing levers 13 and 14 are arranged one at'each end of the frame, are I pivoted to one side of the latter, and move in guides 15 on side faces of uprights on the other side of the frame. 'The free ends of the levers 13' and 14 are bent later ally,

s the belt may at. 16, about the uprights and have the lower ends of coil springs 17 secured thereto,

levers and x pairs, etrch the upper ends of the springs being secured at 17, to the adjacent uprights so as to hold 1 the levers "l3 and 14 in elevated positions. Both-oi thetreedles are connected to the is vers 13 and l lYas hylinks i8,rpivoted to the to the trecdles anderranged in air being at opposite ends of the ame. It lsfap arent that the depression of either treadle' W lcause the mother, thusenahling themachine to he opnieterielto one side of the machine.

. spaced to permit dies, engages the teeth the belt at one end of the letter 01 rollers. 30 formed depression of the eret'ed from either side. The treadles are connected to onset the rollers, in this instance to roller 7 by an intermittent driving-connection, preferably in the form of a stra 19 having oneend secured'at 20 to one of t e treedles and its other end secured to and passing about a drum 21. Drum 21 turns oil-the shaft of the roller and carries a pawl 22 which, when the drum is rotated in one direction by the depression of the trea- 011a toothed wheel or ratchet 23 rigidly secured to the roller shaft, and causes the'rotetion of the roller 7 end the movement of the belt B. The drum is rotated .in the other direction by a helical spring 24 surrounding the shaft ol'roller "Z and secured at one end to the drum '21 and at its other end to a flanged hearing 25 in which the shaft turns.

. The articles to be separated are fed onto and are prevented from moving oil the belt, either at thisend or at the sides, by a. hopper 26 open stone end. and side hoards 2? extending along the sides or the belt from the open end of the hopper. The smeller articles drop through the upper portion of the separating hell; B, onto a receptacle arranged below this portion of. the belt. This receptacle is preterably in the form of e chute to discharge the As a preferred end novel form of chute t3, 1 employ a: plurality of curved slots 28 arranged transversely to, the incline of the chute, the curvature of the slats gradually increasing from one side of the machine to the other. The slats are preferably connected by cross strips 29 and are secured at their ends to the two end cross pieces 3 which, for this purpose, are beveled so that the ends of the slats may lie properly. The slats are preferably the discharge 0. dirt and other eitraneous matter.

From thehopper 26 the larger articles are carried by the belt to the opeh end oi the machine, where they are discharged into any suitable rece tools. in moving to the discharge end, t e articles on the belt pass successively over movable agitators in the form with rows of trusto-con ical projections 31 which are adapted to pass through successive rows of the rings and thus tohe carried along by the belt. These proiections 31, together with the roll surface,

\ disinetl oi space iiicioserl seemed cause the displacement of any articles in the openings lot the helt, and this displacement place so gradually that theerticles nctlhruised.

in some instances the articles will become jammed in the belt openings and will be car-- ried again to the feeding end of the machine, and, as the hopper must be closed. at this end to prevent the of the articles, some means must he provided to permit the articles to move past the hopper well with the belt, as, otherwise, the articles would engage said wall and. cause damage to the delicate belt or to other parts of the machine. To overcome this ditliculty 1 construct the hopper with s yielding" wall preferably in the form. of a door 32 hingedct so as to swing subject matter lacing separated.
